A transceiver array that employs vertically integrated circuits in one or more wafers. The array includes a digital wafer having digital circuits. A plurality of RF cubes are formed to the digital wafer, where each RF cube includes an antenna wafer and at least one lower wafer, and where each RF cube represents a separate channel of the array. The antenna wafer includes a patch antenna and a resonating cavity. The at least one lower wafer includes high frequency RF integrated circuits and intermediate frequency RF integrated circuits. The array has application as a front-end for a digital beam-forming system.
